s. R. GOULD 1,750,8(1 -a3 Patented Mar. 18, 1930 UNITED STATES PATENT oFFIcE SYDNEY B. GOULD, O1? BAKERSFIELD, CALHORNIA VACUUM-CLEANER ATTACHMENT FOR A'UTOMOBILE ENGINES Application filed January 18, 1927. Serial No. 161,887.

My invention relates to and has for its purpose the provision ternal combustion engines of motor vehicles by which the suction created in the intake 5 manifold thereof can be utilized to perform the function of a vacuum cleaner in effecting cleaning of the interior of the automobile to which it is attached or by a suitable extension to permit the attachment to be used interiorly of a dwelling.

It is also a purpose of my invention to rovide an attachment of the above described character which and dirt accumulated in the attachment from 5 passing to the intake manifold of the engine, so that the engine can function in the normal manner.

I will describe only two forms of vacuum cleaner attachments for automobile engines 20 embodying my invention and will then point out the novel features in claim.

In the accompanying drawings,

Figure 1 is a view showing in vertical section one form of vacuum cleaner attachment 25 in applied position to the intake manifold of an internal combustion engine;

Fig. 2 is an enlarged detail sectional view illustrating a detachable connection between a conduit embodied in my invention and the intake manifold of the engine.

Figure 3 is a view similar to Figure 1 showing another form of attachment embodying my invention. I

The embodiment of my invention shown in igure 1 comprises a tank including a lower section and an upper section 16 detachably connected to each other and both of which are closed at their remote ends so that when they are assembled the will form a complete closed tank. Within the lower section is contained a body of water 18 or other suitable liquid and to the top of the tank is connected a pipe 19 for communication with the interior thereof above the liquid, the upper end 45 of the pipe extending through the top of the tank for connection with a rigid or flexible pipe 20 of suitable length for connection to the intake manifold 21 of an internal combustion engine 22 of a motor vehicle. A conventional union 23 is employed to connect the of an attachment for in operates to prevent the dust 20 is free of any foreign matter and may ass pipe 20 to the intake manifold and in such manner that when the attachment is not in use the pipe 20 can be disconnected from the intake manifold, and a cup (not shown) ap-' plied to the nipple of the manifold to close 56 the latter, as will be understood. A hose 24 is connected to a length of ipe 24" extending throu h'the top of the tank into the body of liqui the opposite end of the hose being provided with a nozzle 25 of the same construction as the conventional vacuum cleaner nozzle.

In the operation of the attachment, the suction created in the intake manifold'during the normal operation of the engine is utilized to create an induced suction 1n the ipe 20 and, hence in the pi 119, thereby rawing air upwardly of the l tter pipe and creating a partial vacuum within the tank. This partial vacuum operates to create a suction in the pipe 24 and consequently, at the nozzle 25, so that dust and other matter will be sucked into the nozzle through the hose and into the body of liquid. The air dischar ed into the tank will pass upwardly througi the water and upwardly into the pipe 19, and during its passage through the water will be filtered of any foreign matter. Thus the air finally delivered to the intake manifold through the pipe into the engine without the possibility 0 interfering with the normal operation of the on me.

n Figure 3 I have shown another form of vacuum cleaner attachment embodying my invention which comprises a tank formed of a lower section and an upper section 31 with a filtering screen 32 interposed between the sections. The pipe 34 extends upwardly through the bottom of the section 30 and 90 through the screen 32, its upper end being disposed within the upper section 31. The lower end of this pipe 34 is connected to a length of flexible pipe 35 which corresponds to the pipe 20 and is adapted for connection by means of a. union 36 to the intake manifold 21 of the internal combustion engine 22.

A second pipe 37 extends upwardly through the bottom of the section 30 with its upper end terminating below the screen 32 and above a body of water 38 contained in the lower section. At its lower end the pipe 37 is connected to a hose 39 having a nozzle 40. In the operation of the attachment just de- 5 scribed the induced suction created in the pi e 34 operates through the tank to create an induced suction in the pipe 37 which is transmitted to the hose 39 and the nozzle 40. Thus dust and other matter may be drawn through 10 the nozzle and discharged into the tank through the pipe 37, the screen 32 operating to filter the air as it passes through the tank and into the upper end of the pipe 34'so that the air finally delivered to the intake mani- 15 fold through the pipe 35 is free of any foreign matter an may be delivered to the engine without interfering'with the-normal operation of the latter. The dust caught b the screen 32 will fall into the water 38 an thus 29 be moistened, so that an accumulation-of the dust will take place on the body of the water rather than on the surface of the screen, thereby preventing clo ging of, the screen and insuring its proper tering operation at 25, all times.

Although I have herein shown and described only two forms of vacuum cleaner attachments for internal combustion engines of automobiles, it is to be understood that 30 v various changes and modifications may be made therein without departing from the spirit of the invention and the spirit and scolpe of the appended claim.

claim as my invention: as In a vacuum cleaner attachment for internal combustion engines, a tank, a body of liquid adapted to contain a filtering' element' in the tank above the liquid, a pipe extendin through and above the filtering element an m ada ted for connection to the intake manifol of an engine to create an induced suction within the tank above the. filtering element, a second pipe adapted for connection to a nozzle and extendin' into the tank to a a point above the litgiidan below the'filterin element, so that t e induced suctioncreate within the tank will be transmitted to the pipe and nozzle and the air discharged into the tank as a consequence will be filtered by so the filtering element in its passage to the first Eipe and the filtered matter deposited on the quid.
